This set includes five steel pinion gears with tooth counts of 10, 11, 12, 13, and 14, all with a 32-pitch (0.8 module) cut and a 3.175mm bore shaft. Each gear is 11mm tall and comes with its own grub screw, plus a hex key for installation. Designed for 1/10 scale crawler trucks, these gears work with motors from brands like Traxxas, Arrma, HSP, HPI, AXIAL, Tamiya, and LOSI. Before installing, confirm that your motor shaft is 3.175mm in diameter and that your spur gear matches the 32-pitch to ensure proper meshing.

How do I know if these gears fit my RC motor?
Two things must match. First, the motor shaft must be exactly 3.175mm in diameter. If your motor has a 2.3mm or 5mm shaft, these gears won't fit. Second, the spur gear in your drivetrain must also be 32 pitch (0.8 module). Gears with different pitches won't mesh correctly and can strip or bind. Double-check your current parts before ordering.
